All,
I'm currently building a custom Content Management system for a site we're
working on, and am stuck. Currently, I am using a couple of classes to run
most of the queries throughout the application. Well, I'm pretty stuck now.
What I need to do is use a variable throughout my classes that is a Session
variable. I really can't find another solution. The syntax I was using for
this variable before (I actually hard coded it during my testing and
development before this point) was this:
class C_DisplayConten t{
var $username = "S_";
function foo(){
//code that uses the variable as $this->username
}//end foo
}//end class
So, what I really need now is to have the variable look like this:
var $username = $_SESSION['username'];
and be able to use it like normal using the $this->username syntax. However,
PHP seems to blow up at it. I've tried numerous ways of doing this
syntactically and I always end up with errors. The current error I'm getting
is:
Parse error: parse error, unexpected T_VARIABLE in
The line is of course the line where I'm assigning the variable.
What am I missing in regards to using session variables within a class? Any
help is appreciated. 3 1362

Since $_SESSION is a superglobal do you really need to assign it to
$username?
or at least try:
var $username = '';
function set_user_sessio n()
{
if (isset($_SESSIO N['username']) && !empty($_SESSIO N['username']))
{
$this->username = $_SESSION['username'];
}
else
{
$this->username = NULL; // or whatever you want
}
}

You can't initialize a class member that way with anything other than a
constant (for the most part). So function calls and other variables
are out. You can, however, initialize it through the constructor:
class foo {
public $username;
public function __construct() {
$this->username =& $_SESSION['username'];
}
}
Note that, because $this->username is assigned by reference, changes to
$this->username will also be reflected in $_SESSION (since they are two
variables pointing to the same value).

Yup - that did it. I actually just killed the username var off and used
$_SESSION['username'] throughout my application. I guess I didn't really
think about it being global already... I'm new to PHP classes, so it's good
to get this knowledge in. Thanks a ton for the help guys :) This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

I'm a VB.NET programmer who is attempting to write my first C# web

In the VB.NET world we can easily save classes in session variables. I'm

I'm building a complex web-based reservations system.
Gathering the user's data requires between 8 and 15 pages (depending on
which options they are interested in). I use the "Session" object to store
the various elements as the user moves through the pages.
Rather than storing the preferences directly in the Session object (e.g.
Session("LastName") = ...), I created a class
